Corrected entry: When Korra gets her bending back, she ends with a massive wave shooting up over the cliff. But there is a difference between the shape of the wave between the two shots: in the first one, there is a sort of notch, through which we can see Korra, but in the reverse angle, the notch is instantly gone, it's just a wall of spray.

Correction:1) That is exactly how it is intended. The white portion of water gets sprayed. The blue portion goes back down. It is unsurprising, especially because Korra is emanating a shockwave. 2) I can see two notches going back down.

Correction:First, "there isn't so much as a scratch" is wrong; we don't know if there was or wasn't a scratch, because the part that gets scratched was not shown. Second, "those are pretty tough" is a personal assumption. (I assume from the real world?) A car is shown to have bent a lamp post. That's evidence that lamp posts in this cartoon world (which is a steam-punk world) are not tough.

Correction:Because it didn't hit her head and the refs are fallible human beings. They just missed it. How many times do referees make bad calls or miss making calls in real life sporting events? This isn't a mistake because it happens in real life ALL THE TIME.

Korra: You have a battleship?Varrick: Of course I do! I bought the first one they made! Named her the Zhu Li.Bolin: You named your battleship after your assistant?Varrick: Yep! They're both cold, heartless war machines.
